What does scientific reasoning reguire

Scientific reasoning requires following the scientific method.
1. You foremost make an observation about the universe.
2. Make a hypothesis as to why that phenomenon is the way it is.
3. Design an experiment to test your hypothesis. Hypotheses can be thought of as "predictions"
4. Finally draw a conclusion based on the results of your experiment. Was your hypothesis proven to be valid?

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
